Filed: 1958-07-08
Abstract: 856,019. Percussive tools. CONSOLIDATED PNEUMATIC TOOL CO. Ltd. July 6, 1959 [July 8, 1958], No. 21843/58. Class 124. A pneumatic percussive drill has a central water tube with a lateral opening communicating with a chamber, one wall of which is movable and an air controlling valve biased towards the closed position is opened by movement of the wall under pressure of water to admit compressed air to the motor of the drill. As shown, water under pressure enters the back head of a drill through a valve 9 and passes into a tube 16 having an opening 17 leading through a passage 19 to a chamber 20 formed between a flange 37 and a cap-shaped valve 39. Air under pressure enters the back head through a valve 2 and a portion passes through a channel 24 to enter a chamber 23 formed between the back head and the valve 39. When the water pressure is at a predetermined value the valve 39 moves against the air pressure in the chamber 23 and allows air to enter the distributing valve of the motor through a passage between a flange 26 on the valve and a seat 29 on the distributing valve casing 3. Should the water pressure fail or be reduced below the predetermined value, air pressure in the chamber 23 closes the valve 39 and operation of the drill is stopped.

Title: Process for the manufacture of very pure hexachlorodisilane
IPC: C01B33/08
Filed: 1959-06-25
Abstract: Hexachlorodisilane is produced by heating trichloromonosilane vapour to 200 DEG -600 DEG C. and cooling the reaction gases immediately to above 30 DEG C. to condense Si2Cl6.  The SiHCl3 may be diluted with inert gas or hydrogen and may <PICT:0923784/III/1> be heated at pressures 1mm. Hg. to several atms. by contact with the surface of hot bodies of silicon, silicon carbide, carbon, graphite, glass, aluminium oxide, quartz, sillimanite, porcelain, metals, alloys, silicides of molybdenum or boron,, or mixtures thereof.  Strips, rods, grids, tubes, spirals, or films may be used.  Alternatively heating may be by induction.  SiHCl3 diluted with H2, N2, or A, is passed at 3 into quartz tube 1 containing graphite rod 2 inductively heated to 600 DEG C. Si2Cl6 is condensed by cooling jacket 10 and coil 4 and flows to flask 5.  Gases escape at 6.  Unreacted SiHCl3 is evaporated from 5 and returned by inert gas, which may be that from 6, entering through 8, to inlet 3.  The Si2Cl6 may be purified by distillation under atmospheric, or sub-atmospheric pressure.

Abstract: 224,844. Marks, E. C. R., (Ateliers de Construction de Chaudronnerie et d'Estampage d'Awans, Soc. Anon.). Sept. 5, 1923. Charging.-In blast-furnace charging-apparatus, of the kind in which tubs 10 are provided, at the point of coupling to the hoisting mechanism, with a cover, the cover is formed with projecting arms 5 which engage with an inverted truncated conical surface 6 forming a stop for the cover and serving to centre the cover, and consequently the coupling member 3, with respect to the tub. The tubs are brought to the coupling point on trucks 11 having a conical seating 12 for the lower end of the tub so arranged that when the truck is brought to the predetermined point the tub is correctly positioned for coupling. The Figure shows the position after engagement of the member 3 with the head 4 and hoisting a short distance; this initial hoisting movement does not effect engagement of the tub with the cover, but serves to cause the joint 3, 4 to move up within a cylinder carried by the cover, thus preventing accidental disengagement.
